IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 191,688, dated June 5,1877; application filed March 23, 1877.

To all whom it may concern:

Be it known that I, L. W. LILEs, of Jackson, Mississippi, have inventedcertain new and useful Improvements in Plows, of which the following isa clear, full, and exact description, reference being had to theaccompanying drawings, making a part of this specification, in which-Figure 1 isa perspective view of a plow Fig. 2 is a rear view of theplow. Fig. 3 is a side elevation.

My invention relates to an adjustment of the set of the plow, eitherdeep or shallow and it consists in the general construction andarrangement of parts, as hereinafter explained and claimed.

To enable others skilled in the art to make and use my invention, I willproceed to describe the exact manner in which I have carried it out.

In the drawings, A represents the plow- Fig. 1, and the standard ispivoted to the beam by the bolt (I. To the rear end of the beam issecured a grooved plate, E, and against this grooved plate is fitted therear standard (3, also constructed with grooves g, fitting into thegrooves in the plate E, as shown in Fig. 2. The standard is held inposition by the screw-bolt e passing through slotted opening e made inthe upper end of the standard 0 and the screw-nut n, as shown in Fig. 3.By means of the slotted opening 6 the standard 0 may be raised orlowered to adjust the set of the plow, and, when properly adjusted, thescrew-nut forces the grooves of the standard into the grooves of theplate E, and the plow is held securely in position. The rear standard Ois also constructed with the offset 0 to bring the body of the standardcentrally under the beam when secured in position.

Having thus explained my invention, what I claim as new, and desire tosecure by Letters Patent, is-- The pivoted standard B, provided with thecircular-faced lug D, and the slotted standard (J, provided with thegrooves g, in combination with the beam A, provided with the groovedplate E, all constructed to operate substantially as and for the purposeset forth.
